They're not 90-degree Arcs.  @leeminardi suggested how to make them so, but that's going to give a rather different-looking end result than your first image.

 

If you want them to be tangent to vertical at their upper left ends, as seems to be the intent in the image, and from the fact that the Y coordinates of your specified center points and start points are the same, but you want your specified points to be their endpoints, do the first one [with points above] this way:

....

arc
145,0  ; start

_end
785,-640

_direction 270

....

 

But note that the center is not specified there, but will be a result  of the rest.  Its Y coordinate will be the same as the start point, because of the direction specified, but its X coordinate will usually not be what you have in your center points.
